SAP Commerce - product registration

[sap-commerce-andreas]

Hi,
we are using the product registration feature in SAP Commerce which is connected to CRM.
Now, we'd like change from SAP CRM to S/4HANA and C4C.
The old CRM world describes the product registration feature for SAP Commerce here: https://help.sap.com/viewer/50c996852b32456c96d3161a95544cdb/1905/en-US/665176af3b0941b986660194bc8c...

I haven't found any references neither in the new SAP Commerce Integration Extension Pack nor on the BTP on api.sap.com. I found the product registration feature only on C4C but there isn't any connection to SAP Commerce.

What is here the new world to support product registration on SAP Commerce with S/4HANA and C4C OOTB?

Best Regards
Andreas
